It's so obvious in these pictures.remove the black wires and solder grey and orange there.where which colour goes is not clear but will become apparent when you run the motor.When it goes the wrong way you have the wires crossed.I understand why the c's are soldered to the body.But that is no concern to you.Just remove them.

John,The yellow "thing" is a capacitor, which as used is part of the RF suppression. Remove both - not needed if locomotive is run in USA.

Black wires – Solder one to decoder Gray: Motor (-) the other to Orange: Motor (+) or desolder the black wires and solder decoder motor wires in their place. Test locomotive for direction of travel before soldering.

Speculation - Looks like a motor that has been cannibalized. The motor is in a motor mount, which looks like a mount used in HO F7-A/B, FT-A/B, F9

I have done the following: . Wired the orange and gray wires of a decoder to the two copper "tabs" where the black wires use to be on the motor. . Removed the two capacitors that were soldered to the motor. . Soldered red wires to right wheel pickup and black wire to frame for left wheel pickup.

When I place the wheels and frame on the test track, nothing happens. No LED light in the decoder which means no power is being recognized. No pickup. I am using my DCS-50 throttle and using JMRI. However, when I have run this motor in DC by just connecting each black wire to a terminal, the motor runs very well. What am I missing here? How is this motor different than Athearn motors when connecting to a decoder??

I still need help from one of you "motor" experts. The motor in questions is shown below again and are also in previous messages. See my notes below:

I have done the following: . Wired the orange and gray wires of a Soundtrax decoder to the two copper "tabs" where the black wires used to be on the motor. . Removed the two capacitors that were soldered to the motor. . Soldered red wires to right wheel pickups and a black wire to loco frame for left wheel pickup. . Made sure the motor and decoder were "isolated" from the frame.

I have 4 of these new motors and would like to use them on Athearn F and GP units.
